Since the Gizmo Project is based on the Session Initiation Protocol (SIP), it can interoperate with other SIP-based networks directly, although some data will always be routed via central SIPphone-servers, making it less than ideal in these settings from a privacy and security perspective.[3] This avoids the phone system and is thus free of charge. Gizmo also will use encryption (SRTP) for Gizmo to Gizmo calls and works well with Phil Zimmermann's new Zfone secure add on.

Free calls to landline/mobile phones

The Gizmo project offers free calls from a computer to the landline/mobile phones of other Gizmo users, but with restrictions that aren't fully disclosed.[5] As a result, accounts can switch between a qualified and unqualified status without notice.
